Unable to obtain truncated responses using --max-print-bytes

[LeeZBug]

Describe the bug
I use 'kyanos watch http --path /site/list' to capture data, it says "truncated, total: 2351bytes"

But when I use "kyanos watch http --path /site/list --max-print-bytes=5120", it not says "truncated, total: 2351bytes", but the response is still incomplete.

To Reproduce
everytime

Expected behavior
It seems that the '--max-print-bytes=5120' parameter is not taking effect.

Screenshots
like above

Hello @LeeZBug! I'm here to help you with any bugs, questions, or contributions you have. Let's work together to resolve this issue.

The --max-print-bytes parameter in kyanos is intended to adjust the limit for displaying the content of requests and responses. By default, content exceeding 1024 bytes is truncated, and this parameter should allow you to change that limit to a different byte size ^[1].

If you're experiencing issues where the parameter doesn't seem to take effect, consider the following possibilities:

1. Parameter Override or Conflict: There might be other settings or conditions in kyanos that could override or affect the --max-print-bytes parameter, although specific details on this are not available ^[1].

2. Implementation or Bug: There could be a bug or an implementation issue with how the parameter is handled. Unfortunately, there are no known issues or bugs documented related to this parameter ^[1].

3. Error Handling or Logging: Check if there are any error messages or logs that might provide insights into why the parameter isn't working as expected. This could help identify if there's an underlying issue ^[1].

Since the parameter should allow for larger content display, and it's not working as expected, it might be worth checking the kyanos documentation or code comments for any additional insights or reaching out to the maintainers for further assistance.

I use '--max-print-bytes=anynumber'(like 3600,10240,20480), but the response is still incomplete. response is always truncate at same line

I'll take some time to work on it.

Hi, @hengyoush The problem is not related to the TUI, and it actually originates from HTTPStreamParser.ParseResponse. We only parse HTTP/1.X and do not handle HTTP/2 which is the root cause.

Hi, @LeeZBug Could you provide your response header ?
